“…Climate change can also affect man-made disasters, including industrial accidents, transport accidents, and miscellaneous accidents (Labovská et al 2014 ; Li et al 2019 ). This paper also analyzes the influences of climate change on man-made disasters from three aspects: temperature change, carbon dioxide, and forest land.…”

“…Nezamodini et al ( 2015 ) proposed that flammability and reactivity of materials, high temperature, operation pressure, and volatility and evaporability of liquids may result in fires and explosions especially for industries with high frequency use of hydrocarbons. Cheng et al ( 2018 ) and Li et al ( 2019 ) pointed out that heavy fog, haze, and sandstorms, leading to low sight visibility, are the main reasons for transport accidents. Therefore, climate change, such as extreme temperatures, fog, sandstorms, heavy rains, windstorms, and so on, will affect the cost of industrial accidents, transport accidents, and miscellaneous accidents, which we refer to as man-made disasters.…”

“…As a typical pollutant in heavy pollution weather, PM 2.5 has become a hot spot of research recently [10][11][12][13]. Beijing-Tianjin-Hebei region [14][15][16][17], the Yangtze River Delta region [18][19][20][21][22] and the Pearl River Delta region [23][24][25] are the three highly air-polluted regions in China. As a result, the incidence of air pollution-related diseases in major cities in these regions has been increasing year by year [8,9,26,27].…”

Steady meteorological conditions are important external factors affecting air pollution. In order to analyze how adverse meteorological variables affect air pollution, surface synoptic situation patterns and meteorological conditions during heavy pollution episodes are discussed. The results showed that there were 78 RPHPDs (regional PM 2.5 pollution days) in Jiangsu, with a decreasing trend year by year. Winter had the most stable meteorological conditions, thus most RPHPDs appeared in winter, followed by autumn and summer, with the least days in spring. RPHPDs were classified into three patterns, respectively, as equalized pressure (EQP), advancing edge of a cold front (ACF) and inverted trough of low pressure (INT) according to the SLP (sea level pressure). RPHPDs under EQP were the most (51%), followed by ACF (37%); INT was the minimum (12%). Using statistical methods and meteorological condition data on RPHPDs from 2013 to 2017 to deduce the thresholds and 2018 as an independent dataset to validate the proposed thresholds, the threshold values of meteorological elements are summarized as follows. The probability of RPHPDs without rain was above 92% with the daily and hourly precipitation of all RPHPDs below 2.1 mm and 0.8 mm. Wind speed, RHs, inversion intensity(ITI), height difference in the temperature inversion(ITK), the lower height of temperature inversion (LHTI) and mixed-layer height (MLH) in terms of 25%-75% high probability range were respectively within 0.5-3.6 m s −1 , 55%-92%, 0.7-4.0 • C 100 m −1 , 42-576 m, 3-570 m, 200-1200 m. Two conditions should be considered: whether the pattern was EQP, ACF or INT and whether the eight meteorological elements are within the thresholds. If both criteria are met, PM 2.5 particles tend to accumulate and air pollution diffusion conditions are poor. Unfavorable meteorological conditions are the necessary, but not sufficient condition for RPHPDs.

“…ere are relatively more studies on the microscopic characteristics of burst reinforcement of fog [23][24][25][26][27]. Li et al [28] summarize the research results of dense fog in China, including the burst reinforcement features of strong dense fog (SDF) formation, the microphysical process of the fog body enhancement, the causes of burst reinforcement, and the characteristics of the boundary layer structure. e study on the long-term variation characteristics of fog and haze from meteorological stations shows that the annual haze day in China shows an obvious increasing trend, while the foggy day shows a decreasing trend [29][30][31].…”

A large-scale persistent strong dense fog (SDF) event that occurred from December 30, 2016, to January 5, 2017, in central and eastern China is analyzed by using a variety of data, including high-resolution satellite and surface observations, meteorological tower observations, fine-resolution sounding observations, and NCEP/NCAR reanalysis data. The results show the following: (1) The SDF event has the characteristics of long duration, wide influence range, large intensity, and serious air pollution. During the study period, there are 531 stations with SDF events, covering an area of over 360,000 km2. There were five stations in Hebei province where the fog lasted for more than 77 hours, and even some stations did not dissipate during the day. (2) Radiation fog and advection fog alternate in this SDF event, namely, radiation fog (20:00 BT on December 30 to 14:00 on January 1), advection radiation fog (20:00 on January 1 to 08:00 on January 2), radiation fog (night on January 2 to daytime on January 3), and advection radiation fog (night on January 3 to January 5). The characteristic of radiation fog is that the central and eastern part of China was controlled by “L” type high pressure. In the stage of advection radiation fog, the combined effect of weak cold advection and radiation cooling leads to the occurrence of SDF. (3) Regarding the duration of the fog event, the inversion structure is continuously maintained at night and in the morning near the stratum, and when the fog intensity is strong, the inversion intensity is correspondingly large, the fog top is lower than the inversion layer top, and the top of the SDF is between 80 and 400 meters.
